title: [Comparative studies of methods for determining organochlorine insecticides and polychlorinated biphenyls].
abstract: The polychlorinated biphenyls are chemical compounds that are similar in their structure and properties to the chlororganic insecticides of the DDT group. The working out of a method for their analysis is important for the veterinary and sanitary inspection of food products of animal origin. Tested were as many as six column-chromatographic methods for the separation of standard solutions of polychlorinated biphenyls (Chlophen A 50 and Chlophen A30) and some chlororganic insecticides. A modified method, based on the method of Snyder et al. was suggested for the separation of these compounds. Much less time was used with it for analysis, and a better reproduction was achieved of the eluted compounds.
